Understanding (how bad) the Exponential Distribution (is)

podcast episode with speaker Chris Jackson

We often use probability distributions to help us characterize the likely values a random variable will have. This includes the random variable we call ‘time to failure’ or TTF, which is how long something works before it fails. Failure is a random process, but just because it is random, doesn’t mean it’s unpredictable. Products that wear-in will have vastly different probability distributions for TTF when compare do products that wear-out. So you need to have a good idea of the probability distribution of the TTF of your product when it comes to reliability engineering. But we often see in textbooks and standards the ‘exponential distribution’ simply being assumed as a ‘good’ TTF probability distribution. But is it? And what happens when it isn’t … but you use it anyway? Join this webinar to find out!

Fundamentals of Hypothesis Testing

podcast episode with speaker Fred Schenkelberg

Let’s make a comparison. Let’s check our product’s key characteristics against specifications, compare vendor life data, or compare the newest design changes to prior performance. We can and should do comparisons well using the appropriate statistical approach.

Let’s examine a handful of parametric and non-parametric comparison tools, including various hypothesis tests. Plus how to best use these tools and when to set them aside and explore another approach.

Using FMEA (or Functional) Block Diagrams to Understand Your Item

podcast episode with speaker Chris Jackson

Many engineers rush to design or build something that we think is ‘awesome’ or at least ‘proves a concept.’ But this often means we build something that we like (not necessarily what our users like) or doesn’t work (because we didn’t realize that have sensitive electronic components near hot exhaust manifolds would be a problem). This is where taking a breath and understanding our product before we build the wrong thing fast can really helpful. A FMEA or functional block diagram can really help us visualize what different parts of our system do, and how they interact. They also help us identify the basic, interface and additional functions that separate an ‘average’ product from an ‘industry leading’ product. If this is something you think you or your team can benefit from, join us for this webinar.

Fundamentals of Process Capability

podcast episode with speaker Fred Schenkelberg

Calculating and interpreting the process capability ratios is the easy part. Getting valid results takes more work and thinking. Knowing that the process is capable is only one use of this information. We should also use the information contained in these ratios to inform product design tolerance. [Read more…]

Using Monte Carlo Simulation
to Make Hard Reliability Analyses Easy

podcast episode with speaker Chris Jackson

Sometimes the equations we need to model reliability are just so complicated that we simply avoid them, or use other equations that are simpler but model the wrong thing (see some of my earlier webinars!). But it doesn’t have to be this way. Monte Carlo simulation is so simple that anyone who has access to Microsoft Excel can use it. What this means is that we don’t need to use complicated equations (like those use to model things like switching systems) and instead can use Microsoft Excel to help us get approximate (but really accurate) answers. Sound interesting? Join us for this webinar!

Fundamentals of Control Charts

podcast episode with speaker Fred Schenkelberg

On one of my first vendor visits, they proudly showed us the control charts behind glass near the conference room. They were nicely printed, all in perfect control, and rather odd. A control chart belongs on the production line, where the operators make the measurements. They are of little value when automatically collected and printed out once a month for display-only purposes. [Read more…]

AI Product Development and Deployment

podcast episode with speaker Greg Hutchins

AI is or will be integrated into every product and service. The world of AI product development is really confusing. What is required? What are good practices? What’s next?

Greg will discuss the critical architecture and design practices that need to be considered in AI product development and deployment. Why should you attend? AI knowledge, skills and abilities are now recognized as a prerequisite for continued employment, development, and promotion for ALL knowledge workers. [Read more…]

The MTBF and Modeling System Reliability

podcast episode with speaker Chris Jackson

The Mean Time Between Failure (MTBF) appears in lots of textbooks and standards, so it must be really important … right? Well, not really. The MTBF is the most overused and misunderstood term in reliability engineering, including system reliability modeling, where we can find textbooks and standards with equations that allow you to calculate system MTBF from component MTBFs. If you are unsure why the MTBF is bad, especially for system reliability modeling, then join us for this webinar, where we will illustrate with pictures (not equations) what the MTBF is and how bad it can be to focus on it as a reliability performance metric.
